Commonly Missed Code Requirements

Please make note of the following commonly missed code requirements:
  • All insulation shall be marked with its R-value (depth markers placed, etc.) or the installer shall post a signed and dated certificate (in the attic near the hatch) that states the type of insulation, its manufacturer, and its R-value, ILHR 22.03(1). Sealing is required at electrical boxes and other penetrations of the insulated thermal envelope.
  • All residential foundations must have drain tile installed to the specifics of ILHR 21.17 (for example, bleeders every 8 feet, a sump crock with pump installed, proper tile location, etc.), unless the owner / builder provides written information on soil type and water elevation exempting it.
  • All residential masonry veneer walls shall conform to ILHR 21.26 (for example, weep holes shall be provided at the bottom course at maximum intervals of 3 feet). The weep holes allow moisture that collects behind the veneer to escape.
  • All submitted plans must show significant detail in order to review. Some examples of inadequate detail include:
    • Incomplete footing or foundation dimensions
    • Incomplete insulation and structural detail (view the building section sheet included in the building packet (PDF)
    • Incomplete stair detail with finished floor heights, etc.
    • Safety glazing not identified
  • Attic hatches located in garages shall be permanently installed with hardware that will maintain it in a closed position when not in use. Screwing the attic hatch shut will work, ILHR 21.08(5)(d)(2).
  • In order to receive an occupancy certificate, all health and safety items related to the permit work shall be code compliant. No occupancy certificate will be given in the following situations:
    • Decks or other elevated areas over 24 inches above grade without proper guardrail protection
    • No handrail is present for three or more risers
    • Unsafe electrical conditions
  • Make-up air (either fresh air intake on the cold air return or an air-to-air exchanger) must be provided to prevent negative pressure from exhaust ventilation, ILHR23.023(3).
  • No one shall occupy a new single-family dwelling prior to a final inspection.
  • Where inadequate erosion control measures exist, all work will be stopped and fines will be levied.
